Global Warming Kills the Planet

Greenland’s Melting
Greenland is melting at a rate of 52 cubic miles per year—much faster than once predicted. If Greenland’s entire 2.5 million cubic kilometers of ice were to melt, it would lead to a global sea level rise of 7.2 meters, or more than 23 feet. [LA Times]

Less Ice in the Arctic
The amount of ice in the Arctic at the end of the 2005 summer “was the smallest seen in 27 years of satellite imaging, and probably the smallest in 100 years.” Experts said it’s the strongest evidence of global warming in the Arctic thus far. [Washington Post]

The Northwest Passage Becomes a Reality
Remember the “Northwest Passage”? For centuries, explorers were obsessed with the almost-mythical idea of northern sea route connecting the Atlantic and Pacific. Well...it’s here. So much of the ice cover in the Arctic disappeared this summer that ships were able to take recreational trips through the Arctic Sea, and scientists say so much of the ice cover will disappear in upcoming years that the passage could be open to commercial shipping by 2020. [CNN]

Ice Shelf in Antarctica Bites the Dust
In 2002, a chunk of ice in Antarctica larger than the state of Rhode Island collapsed into the sea.
British and Belgian scientists said the chunk was weakened by warm winds blowing over the shelf ... and that the winds were caused by global warming. [ENS]

Ice Shelf in Canada Bites the Dust
In 2005, a giant chunk of ice the size of Manhattan broke off of a Canadian ice shelf and began free floating westward, putting oil drilling operations in peril. [Reuters]

Say Farewell to Glaciers
“In Glacier National Park, the number of glaciers in the park has dropped from 150 to 26 since 1850. Some project that none will be left within 25 to 30 years.” [AP]

The Green, Green Grass of Antarctica
Grass has started to grow in Antarctica in areas formerly covered by ice sheets and glaciers. While Antarctic hair grass has grown before in isolated tufts, warmer temperatures allow it to take over larger and larger areas and, for the first time, survive through the winter. [UK Times]

The Swiss Foothills
Late last summer, a rock the size of two Empire State Buildings in the Swiss Alps collapsed onto the canyon floor nearly 700 feet below. The reason? Melting glaciers. [MSNBC]

Giant “Sand Seas” in Africa
Global warming may unleash giant “sand seas” in Africa—giant fields of sand dunes with no vegetation—as a shortage of rainfall and increasing winds may “reactivate” the now-stable Kalahari dune fields. That means farewell to local vegetation, animals, and any tourism in the areas. [National Geographic]

Florida’s National Marine Sanctuary in Trouble
Global warming is “bleaching” the coral in the Florida Keys National Marine Sanctuary, killing the coral, tourism, and local fish that live among the coral for protection. [Washington Post]

The Oceans are Turning to Acid
It sounds like a really bad sci-fi movie, but it’s true: The oceans are turning to acid! Oceans absorb CO2 which, when mixed with seawater, turns to a weak carbonic acid. Calcium from eroded rocks creates a “natural buffer” against the acid, and most marine life is “finely tuned” to the current balance. As we produce more and more CO2, we throw the whole balance out of whack and the oceans turn to acid. [CS Monitor]

Say Goodbye to the Great Barrier Reef
According to the U.N., the Great Barrier Reef will disappear within decades as “warmer, more acidic seas could severely bleach coral in the world-famous reef as early as 2030.” [CBC News]

Mediterranean Sea? Try the Dead Sea.
Italian experts say thanks to faster evaporation and rising temperatures, the Mediterranean Sea is quickly turning into “a salty and stagnant sea.” The hot, salty water “could doom many of the sea's plant and animal species and ravage the fishing industry.” [AP]

A Sacred River Dries Up
The sacred Ganges River in India is beginning to run dry. The Ganges is fed by the
Gangotri glacier, which is today “shrinking at a rate of 40 yards a year, nearly twice as fast as two decades ago.” Scientists warn the glacier could be gone as soon as 2030. [Washington Post]

Disappearing African Rivers
Geologists recently projected a 10 percent to 20 percent drop in rainfall in northwestern and southern Africa by 2070. That would leave Botswana with just 23 percent of the river it has now; Cape Town would be left with just 42 percent of its river water. [National Geographic]

Suddenly Vanishing Lakes
What happened to the five-acre glacial lake in Southern Chile? In March, it was there. In May, it was ... gone. Scientists blame global warming. [BBC News]

Goodbye to the Mangrove Trees
Next on the global warming hit list: Rising sea levels linked to climate change mean we could lose half of the mangrove trees of the Pacific Isles by the end of the century. [UNEP]

Volcanoes Blow Their Tops
British scientists warn of another possible side effect of climate change: A surge of dangerous volcanic eruptions. [ABC News Australia]

More Hurricanes
Over the past century, the number of hurricanes that strike each year has more than doubled. Scientists blame global warming and the rising temperature of the surface of the seas. [USA Today]

More Floods
During the summer of 2007, Britain suffered its worst flood in 60 years. Scientists point the finger directly at global warming, which changed precipitation patterns and is now causing more “intense rainstorms across parts of the northern hemisphere.” [Independent]

More Fires
Hotter temperatures could also mean larger and more devastating wildfires. This past summer in California, a blaze consumed more than 33,500 acres, or 52 square miles.
[ABC] [AP]

More Wildfires
Global warming has also allowed non-native grasses to thrive in the Mojave Desert, where they act as fast-burning fuel for wildfires. [AP]

Thunderstorms Get Dangerous
Hurricanes aside, NASA scientists now say as the world gets hotter, even smaller thunderstorms will pose more severe risks with “deadly lightning, damaging hail and the potential for tornadoes.” [AP]

Higher Sea Levels
Scientists believe sea levels will be three feet higher by the end of the century than they are now. [National Geographic]

Burning Poo
As “
shifting rainfall patterns” brought on by global warming “have made northern Senegal drier and hotter,” entire species of trees (like the Dimb Tree) are dying out, making it harder for natives to find firewood. As a result, more people are having to burn cow dung for cooking fires. [MSNBC]

A New Dust Bowl
Calling Mr. Steinbeck. Scientists this year reported the Southwest United States
is "expected to dry up notably in this century and could become as arid as the North American dust bowl of the 1930s," a process which has already started. [ABC News]

Global Warming Makes Us Sicker

People Are Dying
150,000: Number of people the World Health Organization estimates are killed by climate-change-related issues every year. [Washington Post]

Heat Waves and Strokes
Authorities in China say warmer temperatures are responsible for an uptick in heat-wave associated deaths, such as strokes and heart disease. They calculated between 173 and 685 Chinese citizens per million die every year from ailments related to global warming. [MSNBC]

Death by Smog
Three words you really don’t want in your obit: “Death by Smog.” Yet Canadian doctors say smog-related deaths could rise by 80 percent over the next 20 years. And since warm air is a key ingredient in smog, warmer temperatures will increase smog levels. [CBC News]

More Heart Attacks
Doctors warn global warming will bring more cardiovascular problems, like heart attacks. “‘The hardening of the heart's arteries is like rust developing on a car,’ said Dr. Gordon Tomaselli, chief of cardiology at Johns Hopkins University. ‘Rust develops much more quickly at warm temperatures and so does atherosclerosis.’” [MSNBC]

More Mold and Ragweed = More Allergies, Asthma
A Harvard Study in 2004 showed higher concentrations of CO2 in the atmosphere is good news to allergens like mold and ragweed (they love the stuff). And that means higher rates of asthma attacks, especially in kids. [Globe and Mail]

A Resurgence In Deadly Disease
“The World Health Organization has identified more than 30 new or resurgent diseases in the last three decades, the sort of explosion some experts say has not happened since the Industrial Revolution brought masses of people together in cities.” Why? Global warming “is fueling the spread of epidemics in areas unprepared for the diseases” when “mosquitoes, ticks, mice and other carriers are surviving warmer winters and expanding their range, bringing health threats with them.” Ick. [Washington Post]

More Malaria in Africa
“A WHO report in 2000 found that warming had caused malaria to spread from three districts in western Kenya to 13 and led to epidemics of the disease in Rwanda and Tanzania.” [Washington Post]

Malaria Spreading in Western Europe
The World Health Organization warns warmer temperatures mean malaria-carrying mosquitoes are able to live in northern climes, which could lead to a surge in malaria outside the tropics (aka Europe). [BBC]

Malaria Spreading in South America
Thanks to global warming, “Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level.” [An Inconvenient Truth]

Malaria Spreading in Russia
Russians found larvae of the anopheles mosquito, the malaria carrier, for the first time in Moscow last September. [BBC]

Spread of Dengue Fever
Scientists predict warmer temperatures will allow mosquitoes carrying Dengue Fever to travel outside the tropics. Since people in cooler climes lack immunity from previous exposure, that means transmission would be extensive. You get a severe fever, you start spontaneously bleeding, you can die. There is no vaccine. [Science Daily]

Death in the Time of Cholera
Cholera, which thrives in warmer water, appeared in the newly warmed waters of South America in 1991 for the first time in the 20th century. “It swept from Peru across the continent and into Mexico, killing more than 10,000 people.” [Washington Post]

Spread of Lyme Disease
Cold weather no longer kills ticks that carry Lyme Disease. Ticks recently began spreading along the coastlines of Scandinavia, which formerly was too cold for them to survive. Cases of Lyme Disease in the area have doubled since the late 1990s. [MSNBC]

West Nile Virus Home Invasion
Once confined to land near the equator, West Nile Virus is now found as far north as Canada. Seven years ago, West Nile virus had never been seen in North America; today, it has “infected more than 21,000 people in the United States and Canada and killed more than 800.” [Washington Post]
